Takes the pressure

Richard Wolf, working together with pioneering spine surgeons, was the first company to develop a standardized approach to full-endoscopic decompression of lumbar spinal canal stenosis. The Central Stenosis instrument set represents a true milestone of innovation and advancement in spine endoscopy.

A larger endoscope with a correspondingly larger working channel and larger, stronger instruments were necessary for the more extensive bone and ligament resection necessary for this operation. The VERTEBRIS stenosis instrument set is complemented by the universal motor system and a variety of rigid and articulated burrs.

Stenosis technique

In central stenosis surgery, access to the spinal canal is through the posterior interlaminar window. The dilator is guided directly to the ligamentum flavum or facet joint. After placing the working sleeve over the dilator, the operation is performed through the high-resolution HD endoscope under continuous irrigation. The laminae and medial facet are resected and the ligamentum flavum resected on the ipsilateral side, with the option to address the contralateral side through an “over the top” technique. The design of the system is optimized to provide full functionality of instruments under exceptional visualization, but with a narrow profile that minimizes trauma to the soft tissues and neural structures.

Several specialized manual instruments and a variety of high-speed burrs are available with the stenosis set. Large diameter (5.5 mm) Kerrison punches and burrs provide for fast resection of the laminae and facet under full-endoscopic view.

Education

The program is a comprehensive training concept, consisting of different modules that progress physicians toward successful implementation of these innovative techniques in their hospitals or surgery centers.
